A further objectof the invention is to provide an extremely simple and efficient device,

for controlling the motor at some distance therefrom and comprising. essentially a. re

volving cable extending through or along the length of the hose and operated at the nozzle end of the hose to control an electric swit'ch M) for starting and stopping the motor.

' A still further object of the invention is to providea remote control for motor driven gasoline pumps which control will be formed of a few simple and durable parts which will be inexpensive to manufacture and will not easily get out of order.

l/Vith the above and other objects in view the invention consists in certain novel details of construction and combinations of parts hereinafter fully described and claimed, it being understood that various modifications may be resorted to within the scope of the appended claims without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings forming part of this specification:

Figure 1 is a side elevation with parts broken away showing a motor driven gasoline dispensing pump equipped with my improved rotating remote control, V Fig. 2 is a cross sectional view showing the rotating cable and actuating means therefor as well as showing a mercoid switch con- 0 trolled by the cable, and

Fig. 3 is a cross sectional View taken on the line 33 of Fig. 2.

Referring now to the drawingsin which like characters of reference designate similar parts in the various views, a conventional form of gasoline dispensing pump is shown comprising an electric motor pump 10, which is employed to transfer the gasoline from the storage tank through pipes 11 and 12 to 3 a hose 13 which terminates in a delivery the tube is tilted at, an angle, the quicksilver nozzle 14 having therein the usual valve that is opened and closed by a manually operated trigger 15 which extends along of the nozzle.

' In the present embodimentofthe' invention, I preferably employ ame'rcoid switch 17' of the rotary type. This type switch consists ordinarily of a glass tube containing asmallquantity of quicksilver and when the grip 16 V runs to the lower end thereof and makes contact between switch points which are connected by wires 18 to the motor of the pump. When tilted in the opposite direction, the quicksilver flows away from the contacts and opens the circuit to stop the motor.

For operating the switch 17, I provide a rotary cable 19 which preferably extends longitudinally through the hose 13, although 7 the cable may be disposed eXteriorly along the length of the hose and secured thereto in any preferred manner. One end of the cable is connected to the switch. shaft20 which is journaled in a suitable bearing 21' carried in a housing 22 which may be se-' cured to the casing 23 of the mercoid switch and to a T coupling 23 or like device on the supply pipe 12. The cable rotates the shaft 0 as a' unit therewith to tilt the mercoid switch'17 to opener closed positions. j.

Preferably, the manually operatable means for rotating the cable is mounted in a housing 24:. The housingis provided with screw threaded nipples 25 and 26 to engage threaded couplings 27 and 28 on the nozzle and hose I respectively. 7 I v c I Theend of the rotary cable 19 is equipped with a shaft 29 which is jo urnaled in a bearing 30 disposed within thehousing. The shaft is equipped with a pinion 31 which meshes with a bevel gear 32 keyed to a shaft 33, one end of which is journaled. in a bearing 34 carried in the housing; I The opposite end of the shaft is journaled in a bearing 35 carried by a removable face plate 36 which closes anopeningffi'? in the housing.

Through the opening 37 the gear and pinionmay be properly assembled and there-- after may be conveniently inspected. A

gland nut 38 surrounds the shaft exteriorly of the face plate and prevents leakage.

Exteriorly of the gland nut a hand lever 39 is secured to the shaft and extends along the grip 16 of the nozzle to overlie the trig ger thereof, as best shown in Fig. 1. A spring 39 holds the lever released.

The housing '24, as best shown in Fig. 1, is preferably rectangular in; cross section and the face plate 36 is preferably remov ably secured thereby to screws 40. 1 V

The rotary cable 19, as. best. hown Fig 2, is preferably coupled with the pinion shaf 29 by means of a tapered split sleeve- 41 which forms an enlargement of the shaft. The cable is held against sliding longitudinally out of-the sleeve by means of a, lock nut 42 engagedlon the threaded exterior of the splitsleeve. A similar sleeve 43 and lock nut er connects the cable with the sw tch shat-: and unites the cable, and switch 17 Y for rotar movement unit;

In 0 eration when the olerator 'rasus' l I: b tne grip 16 o the nozzle and closes the, fingers upon the trigger it), the palm. of the hand wi l close upon the operating lever 39' whereby both the valve in the nozzle 14 1s,

opened and the rotating cable actuated by means of the meshing gear andpinion 31 t-o-ti t the mercoid' switch and close the lat ter, thereby starting the motor. hen the operator releases his grip upon the trigger and operating lever, the spring 39 will throwback the operating lever 39 to rotate the rotary cable in the reverse direction and open, the switch to stop the motor,
